Lpy is a printing tool with a GUI interface that was designed to support multi-function printer features such as duplex, n-up, staplers, and booklets.

Now many printers have a lot of functions(Duplex,Nup,Staple,Booklets,etc) and become more smallsized and more inexpensive.

But on Linux(UNIX-like OS) these functions are hardly avaliable. The aim of lpy is to make your Multifunction-Printer(a optional Finisher) avaliable.

Here are some key features of "Lpy":
independent of a spooler and a application software in user space.
Any filter of a printing spooler isn't necessary. a frontend of GNU a2ps that converts a text-file to a PS-file.
a printing filter which uses a GS(Ghostscript)
written in Python and PyGTK
uses SNMP(PrinterMIB) if possible for getting printer informations(Errors and Status)
supports PJL commands if possible.
Now some PJL commands are supported. available in UNIX-like OS(Linux,FreeBSD and Solaris,HP-UX,etc)
